较佳的, 所述绝缘层的制作材料为透明绝缘材料。 选用透明绝缘材料, 可防止降低光的透过率, 同时有利于电致变色器件的显示效果。
较佳的, 所述绝缘层的厚度为 1000〜2000埃。 如果该绝缘层太薄, 则可 能会出现因为膜厚不均匀而造成的漏电的情况, 使得电致变色材料沉积在第 二透明电极层以外的区域, 会造成相邻像素间的串扰; 如果该绝缘层太厚, 则会对光的透过率造成影响。
较佳的, 所述电致变色层覆盖第二透明电极层上方的区域。
较佳的, 所述电解质层覆盖电致变色层上方的区域, 用于为所述电致变 色层提供所需的补偿离子。

较佳的, 所述电致变色器件还包括与第一透明电极层相连的开关元件, 用于控制第一透明电极层和第二透明电极层之间产生电流。 具体的, 所述开 关元件可以为薄膜晶体管、 继电器等具有控制开关功能的器件。 每个开关元 件用于控制一个所述第一透明子电极和与该第一透明子电极相对应的第二透 明子电极之间产生电流, 使得位于所述该第一透明子电极和与该第一透明子 电极相对应的第二透明子电极之间的电致变色材料的颜色发生变化。
所述电致变色器件还包括至少一条连接线, 所述连接线位于绝缘层和第 二衬底基板之间, 用于在纵向上连接多个所述第二透明子电极。 较佳的, 所 述连接线的制作材料为金属材料, 因为金属材料具有良好的导电性, 可以减 小该连接线的电阻, 利于信号的传输。 当然所述连接线还可以使用如氧化铟 锡 (ITO) 等其它导电材料制作。

下面将结合本发明实施例中的 Pft图, 对本发明实施例中的技术方案进行 清楚、 完整地描述。 显然地, 所描述的实施例仅仅是本发明一部分实施例, 而不是全部的实施例。 基于本发明中的实施例, 本领域普通技术人员在没有 做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例提供的电致变色器件, 其剖面结构如图 3所示。 从图 3中 可以看出, 所述电致变色器件包括: 第一衬底基板 301、 第二衬底基板 302、 第一透明电极层 303、 第二透明电极层 304、 绝缘层 305、 电解质层 306和电 致变色层 307。 图 4为完成第一透明电极层 303制作的第一衬底基板的平面 结构示意图。 从图 4中可以看出, 所述电致变色器件还包括: 栅线 308、 数 据线 309和多个薄膜晶体管 310。 图 5为完成第二透明电极层 304制作的第 二衬底基板的平面结构示意图。 认图 5中可以看出所述电致变色器件还包括 多条连接线 311。
具体的, 所述第一衬底基板 301与第二衬底基板 302相对设置。 所述第 一衬底基板 301与第二衬底基板 302可以由相同材料或者不同材料构成, 可 以均为或独立地为玻璃基板、 石英基板或塑料基板等透明基板, 本发明不做 限定。
所述第一透明电极层 303和第二透明电极层 304设置于所述第一衬底基 板 301和第二衬底基板 302之间, 且所述第一透明电极层 303和第二透明电 极层 304的制作材料可以相同也可以不同, 例如, 可以均为氧化铟锡 (ITO ) 等透明导电材料。 此外, 在制作第二透明电极层 304时, 可使用二氧化钛对 其进行修饰, 所述二氧化钛充当离子储存器。
如图 4所示, 所述第一透明电极层 303位于第- -衬底基板 301上方且面 向第二衬底基板 302的一侧, 并且所述第一透明电极层 303包括多个呈矩阵 排列的第一透明子电极 303a。 如图 5所示, 所述第二透明电极层 304位于第 二衬底基板 302上且面向第一衬底基板 301的一侧, 并且所述第二透明电极 层 304包括多个呈矩阵排列的第二透明子电极 304a。 所述每个所述第一透明 子电极 303a与一个第二透明子电极 304a相对应。
所述绝缘层 305位于第二衬底基板 302上方且面向第二衬底基板 302的 一侧, 并且覆盖第二衬底基板上除第二透明电极层以外的其它区域。
该绝缘层 305的制作材料为透明绝缘材料, 例如, 氧化硅、 氮化硅等。 由于所述绝缘层 305 自身的绝缘性质, 使得在后续工艺过程中可以利用电沉 积方法制作电致变色层, 且电致变色材料只能沉积到有电荷聚积的第二透明 电极层 304的表面, 在第二透明电极层 304表面形成电致变色层, 有效地防 止了相邻的像素间发生串扰。 同时, 使用电沉积方法制作的电致变色层的厚 度均匀, 进一步提高了电致变色器件的良率和性能。
所述绝缘层 305的厚度为 800 6000埃。如果该绝缘层 305太薄, 则可能 会出现因为膜厚不均匀而造成的漏电的情况, 使得电致变色材料沉积在第二 透明电极层 304以外的区域, 会造成相邻像素间的串扰; 反之, 如果该绝缘 层 305太厚, 则会对光的透过率造成影响, 进而影响电致变色器件的显示效 果。 较佳的, 该绝缘层 305的厚度为 1000〜2000埃。
所述电致变色层 307位于所述第一透明电极层 303和第二透明电极层 304 之间。 具体的, 所述电致变色层 307位于第二透明电极层 304的上方且面向 第一透明电极层 303的一侧,并且覆盖所述第二透明电极层 304上方的区域。 所述电致变色层 307的制作材料为聚苯胺、 聚噻吩或者其衍生物等高分子导 所述电解质层 306位于所述第一透明电极层 303和所述电致变色层 307 之间, 且覆盖电致变色层上方的区域。 所述电解质层 306的制作材料为包含 高氯酸铝的凝胶型溶液。
所述栅线 308位于第一衬底基板 301上方—且.面向第二衬底基板 302的一 侧, 用于连接橫向排列的多个薄膜晶体管 310的栅极。
所述数据线 309位于第一衬底基板 301上方且面向第二衬底基板 302的 一侧,其与所述栅线 308交叉设置,用于连接纵向排列的多个薄膜晶体管 310 的源极。
所述电致变色器件还包括与所述第一透明电极层 303相连的开关元件, 用于控制所述第一透明电极层 303和第二透明电极层 304之间产生电流。 需 要说明的是, 所述开关元件可以为薄膜晶体管, 继电器等具有控制开关功能 的器件, 本发明不做限制。
具体的, 以开关元件为薄膜晶体管为例进行说明。 所述薄膜晶体管 310 位于第一衬底基板 301上方且面向第二衬底基板 302的- -侧, 所述每一薄膜 晶体管 310的漏极与一个第一透明子电极 30¾相连,用于控制所述第一透明 子电极 303a和与该第一透明子电极 303a相对应的第二透明子电极 304a之间 产生电流。
所述连接线 31 1位于第二衬底基板 302和绝缘层 305之间, 用于连接纵 向排列的多个所述第二透明子电极 304a, 以及用于为与之相连的第二透明子 电极 304a提供电压信号。 所述连接线 311的制作材料为铜、 铁或铝等金属材 料, 因为金属材料具有良好的导电性, 可以减小该连接线的电阻, 利于信号 的传输。 此外, 所述连接线 311的制作材料还可以为如 ITO等其它透明导电 上述电致变色器件中, 通过设置绝缘层 305, 将不希望沉积电致变色材 料的连接线 311绝缘保护起来, 使得电致变色材料只能沉积到第二透明导电 层 304的表面, 有效的防止了相邻像素间的串扰。
本发明实施例提供了一种所述阵列基板的制作方法, 所述方法包括: 在第一衬底基板上方且面向第二衬底基板的一侧制作第一透明电极层, 在第二衬底基板上方且面向第一衬底基板的一侧制作第二透明电极层;

下面, 以本发明实施例提供的电致变色器件为例, 详细介绍本发明所述 电致变色器件的制作方法, 该方法具体包括:

第三步, 如图 5所示, 在第二衬底基板 302的上方且面向第一衬底基板 301的一侧形成连接线 311和第二透明电极层 304。
第四步, 如图 6所示, 在完成第二透明电极层 304制作的第二衬底基板 上沉积一层透明绝缘材料, 并通过构图工艺形成绝缘层 305, 所述绝缘层 305 位于第二衬底基板 302上方 i面向第一衬底基板 301的一侧, 并且覆盖第二 衬底基板上除第二透明电极层以外的其它区域。
第五步, 如图 7所示, 将完成绝缘层 305制作的第二衬底基板放入电致 变色材料溶液中, 通过电沉积过程, 使得电致变色材料沉积到第二透明导电 层 304的表面区域; 电沉积过程完成后, 将该第二衬底基板取出, 并清洗掉 第二透明导电层表面的上残留的电致变色材料溶液, 由此形成电致变色层 307, 如图 8所示。
第六歩, 如图 9所示, 在完成电致变色层 307制作的第二衬底基板上制 作电解质层 306。 在具体实施过程中, 通过丝网印刷工艺, 将凝胶型电解质 溶液涂覆到电致变色层表面, 由此形成电解质层 306。
第七步, 将完成第一透明电极层 303制作的第一 -衬底基板和完成电解质 层 306制作的第二衬底基板对盒。
经过以上步骤, 即可制得上述的电致变色器件。
需要说明的是, 第一步和第二歩相对于其他歩骤的顺序仅仅是示例性的 说明, 其具体可以根据实际生产的需要, 位于第七步之前完成即可, 本发明 对此不做限制。 例如, 第一歩和第二步可以位于第≡步、 第四歩、 第五步甚 至第六步之后或者同时完成, 只需要保证第一歩位于第二步之前的相对顺序 即可。
本发明实施例还提供了一种显示装置, 所述显示装置包括上述的电致变 色器件。 所述显示装置可以为: 例如, 手机、 平板电脑、 电视机、 显示器、 笔记本电脑、 数码相框、 导航仪等任何具有显示功能的产品或部件。
